Is it possible to design a surgical (dental) implant guide in Blender 2.80?
I do not know many things in the dental field, but this should put you on the right track, the answer is yes, you can model what you are looking for, but it is necessary to see exactly what you want to be able to help you improve your model

but it is not in 2.8, it is in 2.79 and in addition to this there is another addon especially for the design of dental bridges, as soon as I remember the name I will provide it
